JOSIAH DORSET'I, OF CHRISMAN, ILLINOIS.

.PULVERIZER OR CULTIVATOR.

SPECIFICATION forming part of Letters Patent N0- '780,'78 5, dated January 24, 1905.

A Application filed August 20, 1904. Serial No. 221,533.

To all whom t may concern.-

Beit known that I, JosIAH Donsn'rr, a citizen of the United States, residing at Chrisman, in the county of Edgar and State of Illinois, have invented certain new and useful Improvements in Pulverizers or Cultivators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same.

'My invention relates to a combined roller and soil-pulverizer or cultivator; and it consists of certain novel details of construction and arrangement of parts, as will be fully set forth in the following speciiicatiomreference being had to the accompanying drawings, in which- Figure 1 shows a top plan view of my invention complete ready for use, there being two of my rollers and pulverizers coupled together. Fig. 2 is a side elevation of .my invention complete ready for use. Fig. 3 is a sectional view of. part of myinvention as takenV on line 3 3 of` Fig. 2. Fig. 4 is a cen-.

tral sectional view of my invention as taken on lline 4 4 of Fig. 1. Fig. 5 is a detail view of the seat-support. Fig. 6 is a perspective detail view of one of the cutting-blades. Fig. 7 illustrates. partly in section, the end of one of the cutting-blades and means for mounting the samein its operative position, While Fig. 8 shows a detail perspective view of a different form of cutting-blade and means to adjust the same.

In order to refer tothe details'of my invention and other parts cooperating therewith, I will employ numerals, andreferring to the numerals on the drawings, 1 designates sec-' tions of the carrying-frame, each of which is bent upward, as indicated by the numeral 2, somewhat in the form of a sled-runner, and near the forward end of said frame-sections I mount theshaft 3, which is provided with a plurality of cutting-disks 4, designed to act` per edge of each bracket I provide a bearingseat 6 to receive the shaft or journal 7 of the pulverizing-roller 8, whichmay have an entirely smooth face or may be provided with a plurality of longitudinally-disposed cuttingribs 9, whereby any of the clods or particles left by the cutting-disks will be thoroughly crushed and pulveriZed.

To insure a more perfect stirring action or pulverization of the soil, I provide a plurality of plow-like blades .or Scrapers 10, each having a journal 11 at each end. to lit into a suitable aperture provided in the frame-sections 1, and in order that said blades may be held at any desired angle I secure to the rear edge thereof the controlling-arm 12, which is provided at its upper end with the controlling-handle 13 and with the thumb-lever 14.

The thumb-lever 14 is operatively connected with the detent 15 bythe link 16, the said detent being designed to cooperate with the rack-bar 17, carried by one ofthe frame-sections, and it is therefore possible for the cutting-blades to be readily moved, so that they willdtake deeply or lightly into the soil, as des1re In the rear ends of the frame-sections 1 I provide a pair of cross-bars 18 and 19, each of said bars being provided with a plurality of teeth 20, and these bars are connected together by the controlling-link 21, -which latter lis provided with an extension or lever 22. It therefore follows that by moving the lever rearwardly or forwardly the teeth 20 maybe correspondingly inclined as desired, so that` A26 by the link 27, said detent being designed to cooperate with the rack-bar 28, so that the controlling-lever 22 will be held in an adjusted position.

IOO

The cutters or blades 10 are also provided at each end with the brackets 29, each having a plurality of apertures 30, whereby the setscrew 3l, passingI through an aperture in the carrying-section 1, may have its threaded end seated in one of the threaded apertures 30, whereby the cutting-blade 10 may be rigidly held in an adjusted position, thereby taking the strain off of the controlling lever or arm l2.

I also provide suitable standards 3 2 at each end of the pulveriZing-roller 8, said standards having the cross-bars 33 and 34, upon which vare permanently secured the members 35 and 36, designed to afford a support for the seatsupporting spring or bracket 37, thus enabling the seat 38 to be secured upon said spring, as will be clearly obvious.

rIhe ends of the spring, it will be observed. pass through the retaining-seats 38, and being provided Witha compensating slot 39 the ends of the spring are left free to play incident to the use of the machine. The seat 38 is also provided with a depending foot-rest 40 for the accommodation of the driver.

A draft-bar 4l is connected in any suitable Way to the upper ends of the curved terminals 2 and the draft-animals attached to the swingletrees 42, a suitable doubletree 43 serving to connect said swingletrees with the draftbeam 4l, as shown in Fig. l.

In Fig. 3 it will be observed that the caster bracket or arm 24 is passed through an aperture in the end of the clamping member 44, said clamping member being passed through an aperture in the extension or bracket 45, which is bolted or permanently secured, as by the rivet 46, to the rear end of the frame-sec tion l, and it is therefore obvious that by turning the nut 47 home upon the threaded terminal 43 the arm or bracket .24 will be reliably secured in position. It therefore tollows that the carrying-wheels 23 may be adjusted relative to the plane of the frame-section to which it is attached.

In Fig. 8 I have shown the cutting-ldmle1() as substantially V-shaped, the same being se cured to the runners l by means of bolts 4f) engaging the free ends ol said blade and passing up through suitable openings 50 in said runners. The runners are also provided with transverse slots 5l, which intersect the slots 50, in which are located adjusting-nuls 52, which are adapted to cooperate with the bolts 49 and raise or lower the blade l0.

Believing that the advantages, construction, and manner of using my invention have thus been made clearly apparent, further reference to the details thereo]c is deemed unnecessary.

That I claim as new, and desire to secure by Letters Patent, is-

The herein-described combined roller and pulverizer comprising` a frame; a pulverizingroller rotatably mounted in said trame; a plurality of cutting-disks having a shaft 3 located in the forward ends of the fralmB-section; cutting-blades l() and means to adjust the same whereby they will take deeply or lightly into the soil; carrying-wheels for the rear ends ol. the frame-sections and a pair of toothed bars movably mounted transversely to the framesections and means to adjust said toothed bars whereby the teeth may be projected forward or inclined rearwardly, and additional means` to adjust the cmrying-wheels for the rear ends of the frame-sections, all substantially as specified and for the purpose set forth.

In testimony whereofl I have signed my name to this speciiication in the presence of two subscribing witnesses,

JOSIAH DORSE'IT.
